Grass invasions and negative effects Changes in
disturbance regimes
Loss of biota (through competitive exclusion, habitat change)
12 Plots Maintained monthly since January 200812 Micromet stations at each (PAR, Soil Temp, Soil Humidity)1 Meterological Statioon (Air Temp, % Rel Humidity, Precipitation)
Areas invadidas de pasto: implicaciones para Harrisia
